Prospects for using composite preparations based on silica nanosols

Abstract Composite preparations were created for foliar feeding of winter wheat using obtained silica nanosols and lignin fugate after coals carbonization. Both laboratory and vegetative studies have confirmed the effectiveness of created preparations for foliar treatments of Cubus winter wheat ( T riticum aestivum L. ). When applied, the preparations enhanced the moisture-holding capacity of leaves, photosynthetic processes of the leaf apparatus, and biosynthesis of organic matter, compared to the control group. Additionally, the studied compositions increased the content of endogenous antioxidants, such as carotenoids in plants, and reliably contributed to the reduction of peroxidation processes in cell membrane lipids. Their use could increase the drought resistance of wheat plants.
